摘　　要：文章主要探讨了涉及VRML编程的若干关键技术问题,包括:交互下的虚拟感知传感、虚拟人体三维模型、整合Java Applet编程应用等方面。感知传感节点包括VisibilitySensor、ProximitySensor以及Collision节点,主要用以感知场景中的用户是否可见其中的造型或与造型的接近程度以及是否发生碰撞;H-ANIM格式主要构造Web浏览模式下三维人体的分层结构;EAI则主要用于在VRML场景与外部环境之间建立起通信通道,直接扩展VRML的环境交互能力和编程能力。This paper discussed some key techniques in VRML programming, including virtual apperceive sensor,three dimension human body model,Java Applet application etc.There are three apperceive sensor nodes in VRML.They are Visibility Sensor,Proximity Sensor and Collision node.They are mainly used to sense objects whether user visible or their closeness with user,also whether happen collision.H-ANIM format is mainly used to construct three human body structure on www browser.And to build correspondence channel between VRML scene and external world is EAI's function.EAI directly extends VRML's environment interaction ability and programming ability.
